Hey guys, just started running into an issue with my Buffalo nfiniti HP-300NH router. Since I started trying to play CoD Black ops, possibly before but never paid attention to my ping in most games, I have been getting ping spikes from 300-1000ms every 8 seconds exactly. If I disconnect the router and go straight through the modem the ping spikes stop... I have upgraded to the newest non DD firmware, I have never used the DD firmwares so Im not sure if I wanna delve into that yet.

My question is what settings would cause a lag spike every 8 seconds? I thought maybe it was something to do with shaw or my PC, but considering the direct line to the modem fixes it I guess its router.
